During one of your observations for the Kearsarge, you measure a temperature of 12 °F and 18-knot winds. The ice that is forming on the ship's surfaces is depicted in the image. During the past 35 minutes, the ice thickness has reached 3/4 inches. How would you encode this observation?
The ice is present is rime ice.
Ice accretion: The ice is building up as a result of strong winds blowing spray onto the ship (Is = 1).
Ice thickness: The ice thickness has reached about 3/4 inches EsEs=02).
Rate of Accretion: Because the ship surfaces accumulated 3/4 inches of ice in 35 minutes, the rate of accretion is rapid (Rs=2).
